SEE WHERE YOUR LAP TIME GOES Created by a professional racing driver and instructor. Mount your iPhone, drive your session and get every lap timed, onboard video with telemetry and a corner-by-corner breakdown: where you braked too late and where you lost speed on exit. VIDEO WORTH SHARING Record with iPhone cameras or connect a GoPro. G-Box overlays lap time, speed, G-forces, track map and RPM on your video. Pick a race-car style dash or a vertical layout for social media. On supported iPhones, film both cameras at once: the road and the driver. ALL ON ONE IPHONE 25 Hz Fusion combines the iPhone's GPS and motion sensors to calculate a smooth driving line between GPS fixes, with no external receiver. These are calculated positions, not 25 Hz satellite measurements; results depend on GPS reception and phone mounting. Add a compatible OBD adapter for RPM, estimated gear and power, or an external GPS receiver: G-Box, RaceBox Mini, Mini S and Micro, and selected Dragy models. COMPARE YOUR LAPS • Automatic lap timing, live delta, sectors and predicted lap time • Speed, G-forces, RPM and delta on synchronized graphs and map • Braking, turn-in, apex and exit speed against your best lap • Friction Circle and a theoretical best lap from your strongest sectors • Session replay on 2D and 3D maps YOUR DATA, YOUR WAY Import sessions from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC and AiM. Export to GBO, CSV, VBO, GPX and NMEA. TRY IT BEFORE YOUR TRACK DAY Open the included Nürburgring Nordschleife demo lap (8:06) to explore maps, graphs and lap timing before your first session.
